Abstract
Embodiments of the present invention are related to an electrical system with a capacitor element and to a method for operating at least one capacitor element in an electrical system, wherein at least one sensor is configured to measure at least one parameter chosen from device parameters and environmental parameters, a processing unit is configured to process the at least one parameter and to evaluate a capacitor element information of the at least one capacitor element based on the at least one parameter, and wherein the capacitor element information includes one or more chosen from a capacitance loss, a tangent variation, a stress, a remaining lifetime, a failure condition, and wherein the at least one sensor includes one or more sensors configured to measure one or more gas species that are chosen from gas species that can be created during a pyrolysis event of one or more components of the capacitor element.
